All provisions of the laws of the United States applicable to the assessment and collection of any tax imposed by this title or of any other liability arising under this title (including penalties) shall, in respect of such tax or liability, extend to and be applicable in any possession of the United States in the same manner and to the same extent as if such possession were a State, and as if the term “United States” when used in a geographical sense included such possession. Such tax shall be collected under the direction of the Secretary, and shall be paid into the Treasury of the United States as internal revenue collections; and All provisions of the laws of the United States applicable to the administration, collection, and enforcement of such tax (including penalties) shall, in respect of such tax, extend to and be applicable in such possession of the United States in the same manner and to the same extent as if such possession were a State, and as if the term “United States” when used in a geographical sense included such possession. This section shall apply notwithstanding any other provision of law relating to any possession of the United States. For purposes of this section, the reference in section 28(a) of the Revised Organic Act of the Virgin Islands to “any tax specified in section 3811 of the Internal Revenue Code” shall be deemed to refer to any tax imposed by chapter 2 or by chapter 21. For purposes of this title, section 28(a) of the Revised Organic Act of the Virgin Islands shall be effective as if such section 28(a) had been enacted before the enactment of this title and such section 28(a) shall have no effect on the amount of income tax liability required to be paid by any person to the United States. The Secretary of the Treasury is authorized to make separate payments to the government of American Samoa, the government of Guam, and the government of the Virgin Islands. The payment to the government of a particular possession shall be in an amount equal to the loss to that possession with respect to tax returns for the first taxable year beginning after December 31, 1976 , by reason of sections 101 and 102 of this Act [amending sections 1, 3, 21, 42, 57, 63, 143, 161, 172, 211, 402, 441, 443, 511, 584, 613A, 641, 642, 667, 703, 861, 862, 873, 904, 911, 931, 1034, 1211, 1302, 6014, 6212, 6504, and 6654 of this title and repealing sections 36, 141, 142, 144 and 145 of this title].
